Mechanobiology of mandibular distraction osteogenesis: finite element analyses with a rat model.
Three-dimensional finite element (FE) analyses were performed to characterize the local mechanical environment created within the tissue regenerate during mandibular distraction osteogenesis (DO) in a rat model. Finite element models were created from three-dimensional computed tomography image data of rat hemi-mandibles at four different time points during an optimal distraction osteogenesis p...
متن کاملMandibular midline distraction osteogenesis.
In orthodontics, bone structure, its density and dimensions play an essential role by explaining limitations in magnitude, size and extent of tooth movement. Severe anterior crowding is one of the most frequently encountered dental malocclusions. Its therapy is mostly limited by lack of basal and alveolar bone and it often involves tooth extractions. Mandibular midline distraction osteogenesis ...
متن کاملBiomechanical evaluation of mandibular midline distraction osteogenesis by using the finite element method.
The aim of this study was to evaluate the biomechanical effects of mandibular midline distraction osteogenesis on the mandibular complex by using a 3-dimensional finite element model, whose construction was based on computer tomography scans of the mandible of a 22-year-old man. The computer tomography pictures were transferred and converted to the finite element model by means of a procedure d...
متن کاملAbstract 127: A Mouse Model of Mandibular Distraction Osteogenesis
METHODS: Human umbilical cords were harvested following routine delivery and WJ was isolated and purified. In vitro, WJ derived stem cells were placed in osteogenic differentiation medium for 14 days, followed by Alizarin Red S staining to evaluate mineral deposition. In vivo, we used a rat critical-size alveolar bone defect model to investigate the use of Wharton’s Jelly (WJ) in formation of b...
متن کاملDistraction osteogenesis in a severe mandibular deficiency
OBJECTIVE Distraction osteogenesis is an alternative treatment method for the correction of mandibular hypoplasia. In this case report, distraction with a multidirectional extraoral device was performed to gradually lengthen the corpus and ramus of a patient who had a severe hypoplastic mandible. MATERIALS AND METHODS The patient underwent bilateral extraoral ramus and corpus distraction oste...
